3. The rear printhead cover is interlocked with the upper printhead cover using
locating tabs. The rear printhead cover must be lifted to allow the locating
tabs to part.
NOTE
The knock out panel is removed when the printer is connected to a Temper-
ature Control Module (TCM). If a TCM is not fitted the knock out panel must
be intact, or this would contravene the safety requirements the printer is
tested to. Where the knock out panel has been removed and a TCM is not
fitted, DEK recommends fitting a new rear panel.
4. Once the locating tabs have cleared, pull the cover horizontally away from
the machine.
